First encounteer. How to assign target and fire?

[Mark Yanning (OP)]

Hi guys, Finally got  fight. I'm quite excited, after few years I got an alien ship around earth, and finally I can test combat. (diplomacy didn't work)
So I instant built some small fighters, and intercept the alien ship. Now, The ship is in range of the 10k railguns. How I lock targets and fire? I'm trying hard

drag the target (on the right) to the fire control (on the left) and click open fire.

Thanks, it worked
What I shall do with the life pod and the wreck?

You can give a command to one of your ships like "load survivors" for the lifepods and you can dump them on a planet via "unload survivors" command. I think this also makes "interrogation" and gives intel/espionage points.

For the wreck, you should come back with a ship which has salvage module and you salvage components from it.
